hi all
i`ve got a vectra c 2.0 dti, and just having fixed the water leak, pollen filter, i`ve now got a problem.

the heater doesn`t work at all on any speeds, untill you turn on the heated front screen, then it blows a force 10 gale at you. i`ve seen posts about the resistor pack but they seem to say it`ll still work on 4, whereas mine won`t.

please help!!
